Eating high-calorie foods regularly can make it a challenge to lose weight — even if you spend more time exercising or have a more intense workout. Processed foods such as soda and candy have little to no nutrients.
You'll end up exhausting yourself, feeling lousy and possibly becoming even hungrier due to over-exercising and eating poorly. You might also end up becoming dependent on exercise to burn off the extra kilojoules you eat from junk food.
It depends on how many calories you eat and it also depends on what exercise you are doing. If you are eating above your maintenance calories, then yes you will gain weight. But if you are eating sufficient protein and lifting weights then you will be likely to gain more muscle than fat.
Exercising without eating well can have various consequences, both short-term and long-term. Exercising without proper nutrition can hinder your performance, slow down recovery, lead to muscle loss, weaken your immune system, and make it challenging to manage your weight effectively.
Understanding the nutritional value of the food you eat and being aware of advertising 'tricks' can also help you reduce your junk food intake. Eating junk food, and having sweet drinks, can lead to short- and long-term health complications, including weight gain, diabetes and heart problems.
You may be born naturally small and your low BMI can be due to your genes. You may have a very high metabolism and find it hard to put on weight, even if you eat foods that have a lot of calories. You may not follow a healthy, balanced diet because you forget to eat or cannot afford nutritious foods.
Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue. Furthermore, if you aren't eating right you won't have the energy to do the workouts that lead to muscle gain.
To shed a single pound, you need to achieve a 3,500 calorie deficit. So if you're following the 80/20 ratio, you'd want to burn approximately 750 calories through exercise and cut an additional 3,000 calories through dieting, says Matheny. That's a total deficit of 3,750 calories for the week.
It might be tempting, but skip the drive-through on the way to the gym. Chances are, you'll feel uncomfortably full, and the fat and sugar in most fast food items will keep you from getting the most out of your workout.
Keep in mind that this weight gain might be temporary as your body transitions to a healthier, stronger body composition. Other reasons you might be gaining weight from exercise and healthy eating are drinking more water, increasing your salt intake or heightened appetite.
If you're wondering about weight gain from sleeping post-exercise, rest assured that sleep is a crucial part of recovery and does not directly lead to weight gain. Getting adequate sleep is essential to a healthy lifestyle and can contribute to overall well-being, including weight management.
As long as it fits into your calorie budget, you can eat whatever you want—fad diet or not.
Key takeaways: When you work out too soon after eating, it may cause gastrointestinal (stomach) issues that affect your workout. General guidelines suggest exercising 1 to 2 hours after a small meal and 30 to 60 minutes after a snack to fuel your workout and prevent stomach problems.
When the calories you burn equal the calories you eat, you reach a plateau. To lose more weight, you need to either increase your physical activity or decrease the calories you eat. Using the same approach that worked at first may maintain your weight loss, but it won't lead to more weight loss.
Diet vs exercise for weight loss
According to Colleen Alrutz, health and fitness manager at Piedmont Newnan, diet wins 70% of the time when it comes to shedding pounds. To fast-track your weight-loss results, couple a healthy diet with regular physical activity. Exercise wins when it comes to keeping the weight off.
80% healthy, whole foods, and 20% for fun, less-nutritious treats. The key is consistency over time, not perfection at every meal. So, if one day you have a pizza, no big deal—just aim to get back on track with your next meal.
Yes, eating less with a low-calorie diet puts you on the fast track to weight loss—and an intense exercise routine leads to increased metabolism and decreased body fat. In reality, a crash diet and overzealous exercise routine can be hard to maintain which may lead to more weight gain in the future.
Symptoms and warning signs of overtraining
“It's natural and expected to feel fatigued after challenging training sessions,” Dr. Goolsby says. “But feeling like you aren't recovering between sessions or experiencing overall fatigue and difficulty pushing yourself during workouts can be indicators of overtraining.”
Fast food is convenient and cheap, but you pay a bigger price in the long run. Those burgers, fries, and shakes usually have more fat, calories, and highly processed carbs than your body needs in one meal. This can quickly lead to weight gain and obesity if you eat it often.
